TO ALL WHOMv IT MAY CONCERN:

Be it known that I, JOHN B. OLDERSIIAW, ofthe city of Baltimore, and State of Maryland, have invented certain new and useful Improvements Vin a Portable or Removable and Replaceable Hot-Air Receiver and Conductor,for heating apartments; and I do hereby declare the following to be a full, clear, andexaet description Y of thc same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a perspective view of the apparatus, and Figure 2 represents a. horizontal section through the same. I am aware that many contrivances have been essayed for taking the radiated heat from a stove, and con- -veying it to apartments above for heating purposes, but in all these cases the stove itself isa part of the contrivanee, or the apparatus is so connected to thc steve orfireplace asnot to be removable without disturbing or disarranging the stove or replacc, or some of its parts. 1 do not take the radiated heat from the stove or products of combustion immediately, but take it from the room or apartment in which the stove or fireplace is used, and in close proximity to the stove or fireplace; andthe apparatus may be putin place or removed without disturbing tne stove or fireplace, it having no permanent connection with them.

l To enable other-s skilled' inthe art to malto and use my invention, I will proceed to describe the same with reference to the drawings. i i

I make a crescent-shaped chamber, A, composed of two jackets, B C, and two endpieces, D, each with a. projecting ila-nge, a aand with an exit-pipe, E, whence the het ai-r gathcred'in the chamber is conveyed to the apartment to be warmed by it. The red lines in fig. 2 may represent an ordinary stove, to which the receiver and conductor is applied. It may be supported on any ofthe projecting portions of the stove, or held to it by a wire or band of metal, or rest upon legs, or otherwise independent of the store. Th'e' flanges a a, at the top 4and bottom of the chamber, rest against the stove or fireplace, which leaves a space ofsome three inches, more or less, between the jacket B and the stove, and also spaces at each side the whole height of the receiver, through which spaces the heated air, from th'e room around or near the stove, enters into the space between the receiver and the stove, as show n by the red arrowsvl 1l The jacket B has a. series of holes, c ce, through it, and heated air enters the chamber A through said holes, as shown by the red arrows 2 2, the., and thence passes through the pipe or opening E, and by any ordinary pipe, up to the room to be heated. A damper mayv be put in the pipe E, to control or shut oil' the hot air, when desired to do so. V

One or more of these crescent-shaped receivers may be used in connect-ion with the stove, and are usually placed around or near the portion where the fire is. They may be cheaply made of sheet metal, and easily applied and removed.

Having thus fully described my invention, what I claim, is-

A portable hot-air receiver and conductor, constructed, arranged, and operating in connection with a stove, for the purpose of heating apartments above it, substantially as described.
